Most people (men and women included) have actually had sex for money, only that they did not make it a career or job.
So if you are specifically speaking of sex work, then it is certainly not something you can analyze by typing on your keyboard.
Sex work includes raw ass kinks and fetishes that will tear off a piece of you even after you retire. I wrote of a time I considered it.

And from what my friends who are in the system say, it's not a job I can stomach. I rather stick to dating for convenience. My sexual pleasure always has a benefit attached to it, whether monetary or otherwise. But the comfort of knowing my means of survival isn't tied to the sex is what makes the difference with that of sex work.
